1 Claim. (Cl. 98-40) This invention relates to a novel outlet for use in an air distributing system and from which the distributed air may be discharged into a building.

One object of the invention is to provide a novel and simple construction of air discharge outlet unit for the purpose specified of a construction which lends itself to simplicity and economy in manufacture in the plant and erection in the field.

A further and more specific object of the invention is to provide a novel construction of outlet unit for the purpose specified comprising a pair of hollow shells each constituting one half of the completed outlet box adapted to be assembled to form the completed box and to be subsequently connected together as by welding.

A still further object of the invention is to provide a novel construction of outlet box comprising two half sections connected together and each provided with an opening therein and whose construction is such as to enable the half sections to be assembled in different relationships to dispose the openings either in opposed or adjacent walls of the box and thereby enable the single box to be used as a sill box or a ceiling outlet unit.

With these general objects in view the invention consists in the construction of outlet box for an air distributing system and in the various structures, arrangements and combinations of parts hereinafter described and particularly defined in the claim at the end of this specification.

In the drawings:

Fig. 1 is a diagrammatic plan view of a portion of the preferred form of air distributing system for a building with which the present construction of outlet box may be used either as a sill box or as a ceiling outlet;

Fig. 2 is a sectional detail illustrating the present outlet box used as both a sill box and a ceiling outlet;

Fig. 3 is a perspective view of the preferred form of outlet box;

Fig. 4 is a cross sectional view taken on the line 4-4 of Fig. 3;

Fig. 5 is a front elevation of the present outlet box connected to two widely spaced air cells; and

Fig. 6 is a front elevation of a modified form of outlet box connected to two adjacent air carrying cells.

In general the invention contemplates a novel construction of outlet box for an air distributing system, and as illustrated herein, the outlet box may be used as a component of a sill box unit or of a ceiling outlet unit in the air distributing system illustrated in the United States patent to Goemann No. 2,729,429, dated January 3, 1956, wherein air, and preferably conditioned air, may be distributed through a cellular metallic load supporting floor to be delivered to the present sill boxes or ceiling outlets, all as described in such Goemann patent to which reference may be made. The present construction of sill box contemplates its manufacture in two half sections connected together and with each half section provided with an opening in a wall thereof. Preferably the outlet box is constructed by utilizing two identical half sections and atcnt O.

r 2,841,070 Patented July '1, 1958 assembling the half sections so that the openings in the walls thereof are disposed in opposite walls in the completed unit or in adjacent walls when such an arrangement is desirable as in a ceiling outlet. In the preferred form of the invention the outlet unit comprises an elongated shell of square cross sectional shape and comprises two half sections of identical structure, each having two walls and an open diagonal face. Preferably the diagonal face is provided with a projecting peripheral rim portion, and the two half sections are assembled with the rim or flange portions in contact, and these may be connected together in any convenient manner as by providing a cementitious layer between such rim portions and spot welding the rims together to thereby form an airtight joint between the half sections. It will be observed that the present construction, particularly in its preferrd form, simplifies the manufacture of the outlet unit in that only a single half section is required to be manufactured and the completed outlet unit fabricated by utilizing two of the identical half sections.

Referring now to the drawings, as shown in the Goemann patent and diagrammatically illustrated in Fig. l, the air to be distributed is caused to flow through the risers 10, 12 and through header ducts 14, 16 and crossover ducts 18, 20 to air conducting cells 22 of a cellular metal load supporting floor. The present outlet unit is illustrated in Fig. 2 as a sill box 26 erected upon the upper Wall of one of the air conducting cells 22 of the cellular metal floor and communicates with the interior of the cell to permit the discharge of air from the sill box 26. Preferably the sill box may be connected to the cell 22 by two flanged conduits 30, 32 as shown. A shoe 34 having its flanges engaging the underside of the upper wall of the air conducting cell 22 and to which the conduit 32 may be secured by fastening bolts 35, as shown, comprises one method of erecting the sill box 26. When used as a ceiling outlet, such as 28 shown in Fig. 2, the outlet unit may be connected by a flanged duct 3'7 and elbow fitting 39, and the elbow fitting may be secured to the lower wall of the air conducting cell 22 by a shoe fitting 41 secured by bolts 43 to a flanged sleeve 45 as clearly shown in Fig. 2. Any suitable size or number of openings may be provided in the walls of each half section.

The outlet unit comprises a hollow shell, preferably of metal, made up of two prefabricated half sections assembled together to form an elongated shell rectangular in cross section. Each half section of the shell is provided with an opening 42, and one of the openings in the completed unit may be used for connection to the air conducting conduit 22 and the other opening as a discharge opening through which air may be discharged into the building. Preferably the hollow shell is made square in cross section and formed by the assembly of two identical half sections. Preferably each half section is triangular in sectional shape with an opening in one wall thereof and with the third side of the triangular shaped section constituting an open face preferably provided with a peripheral flange 47 which when two of such units are assembled to form the completed outlet unit may be welded or otherwise secured to the corresponding flange of the second half section and preferably with a cementitious layer between the flanges to insure an airtight joint therebetween. In practice it is preferred to provide one of the openings with a grille section 48 to form a closure for the opening through which air may be discharged into the building, and in practice the opening in the second half section may be disposed opposite the grille section or it may be disposed adjacent the grille section depending upon the particular conditions in the building as to whether it is desired to discharge the air vertically or laterally when the unit is used as a sill box in the manner illustrated in Fig. 2. For some purposes, as shown in Fig. 2, it is 3 desirable that the half sections be assembled so that the connection to the air carrying conduit 22 may be made with the opening disposed in one of the vertical walls of the outlet unit and with the grille section disposed in the adjacent wall of the-completed unit.

The length of the-elongated outlet unit may be varied depending upon the disposition of the air cells and also as to whether or not the outlet unit is to also serve 'as a mixing chamber into which air of different conditions may be introduced to be mixed therein andsubsequently discharged through the outlet opening in the wall of a completed unit. Such a unit is illustrated in Figs. 5 and 6 wherein the air conducting cell 22A may comprise a cold air cell and the air conducting cell 223 a hot air cell as described in the Goeman'n patent above referred to. In such a system the two cells 22A and 228 will be spaced apart a substantial distance, and the hot or cold air caused to flow into the outlet unit through duct connections of the structure above described in connection with Fig.2. Fig. 6 shows a similar arrangement in which the outlet box is of less length than that shown in Fig. 5 because of the disposition of the hot and cold air cells 22A and 22B adjacent one another.

While the preferred embodiment of the invention has been herein illustrated and described, it will be understood that the invention may be embodied in other forms within the scope of the following claim.

Having thus described the invention, what is claimed is:

An outlet box for use as a component of an air distributing system comprising a hollow shell of two identical half sections, each section being generally triangular in cross section and each having an open face, one of the sections having an air discharge opening in one wall thereof and the other section having a pair of inlet openings, an outwardly extending peripheral flange defining the open portion of each half section to enable the sections to be secured together to form a substantially rectangular outlet box, each of the sections being adapted to be secured together to position the discharge opening and inlet opening in adjacent and in opposed relation to one another to thereby enable such openings to be positioned in ditferent positions in the side, top and bottom walls forming in the outlet chamber.
